Power Quality Enhancement in Distribution System using D-STATCOM

Atta Ullah, Abdul Basit, Muhammad Aslam and Naeem Khan


Power quality and the dynamic performance of the distribution system in Pakistan is poor because of weak and out-of-date system. It is unable to deliver the required reactive power in case of various system disturbances. Distribution Static compensator (DSTATCOM) is an important compensator which is able to enhance the power quality and dynamic performance of the distribution system. In order to improve power quality and dynamics performance of the distribution system effectively a more robust and optimal control algorithm is required for D-STATCOM. Hence, in this research work an improved and optimal control algorithm have been designed for D-STATCOM. In improved control scheme SRF theory control is used for the reference current generation. For the generation of gat pulses for VSC of D-STATCOM level shifted PWM scheme have been used because it offers very good performance for reduction of harmonics distortion. The designed device is implemented in MATLAB-Simulink and is capable to deliver good reactive power compensation under various loading environments such as inductive load, capacitive load and under abnormal faults conditions.
